Isn't it so that most Souncarddrivers should be able to do this for you? They might not replace the mixer entirely, but at least offer some sort of extended control panel. Guess it depends on the Soundcard though how good the EQ is.

at least my (Terratec) xFire 1024 (an old card) has it. From my experience, i'd say it depends on the chipset used, not the model. For example, i know that other cards which use the same chipset as my card, also have an EQ built into the drivers.

hmm. My Aureal SuperQuad something-or-other card had an EQ, as does my Hercules Fortissimo III, as does my Nforce2's SoundStorm or whatever they call it. No idea which of them, if any, were hardware EQs on the card itself or just in the drivers.

I'm looking for the same thing. I want a freeware realtime output EQ that "sits" between any playback source (WinAMP, CD playback, Quintessential, etc.) and my soundcard. A "system EQ", in essence. My soundcard is an Echo Indigo, and it does have its own console software which seems to have replaced my Windows mixer. It has some channel managements functions (level, balance, muting) but no equalization. My OS is WinXP.

I looked at Sound Control, but it's only seems to configure hotkeys for channel management functions, but I couldn't find any EQ function in it. I tried using an internet search for +freeware +eq, and looked through the first 70 results that it came up with, but to no avail. Found one, LizzEQ, that turned out to be a Cubase/VST plug-in. I need one that I guess would be a Windows XP plug-in(?). I did find a few non-freeware options, but I'd rather get a freeware solution if one exists.

Preferably something with at least 10 bands per channel (the more the better), at least +/-12 dB adjustment range (+/-15 dB would be even better), with as good/clean sound quality output as possible.

Does such a thing as a freeware system EQ application exist? If not, I guess I can come off $15 to $25 and buy a shareware EQ, but it better be really freakin' good if I have to pay for it!

My favorite volume control, has no EQ but it is great to mute the sound quickly when needed. Check out Slava Glory's Volumetray. The link while editing does not look, but here it is:GlorysoftI have also purchased izotope ozone to do a parametric EQ in addition to Soundblaster's EQ.I do correct for the bass weaknes of HD580 with the SB EQ and I correct for loudness with izotope ozone. Then I am happy.
